TOTAL HEAT EXCHANGE ELEMENT

To effectively use partition plates comprising base materials and moisture permeable films.SOLUTION: A total heat exchange element (30) comprises a plurality of partition plates (31) comprising base materials (32) comprising first principal surfaces (32a) and second principal surfaces (32b), and moisture permeable films (33) provided on the side of the first principal surfaces (32a) in the base materials (32) respectively, and mutually arranged at intervals. First flow passages (36) in which air flows, and second flow passages (37) in which air having a higher water vapor pressure than in the first flow passages (36) flows are alternately formed between the plurality of partition plates (31). In the plurality of partition plates (31), the first principal surfaces (32a) of the base materials (32) are directed to the first flow passages (36), and the second principal surfaces (32b) of the base materials (32) are directed to the second flow passages (37).SELECTED DRAWING: Figure 3 【課題】基材および透湿膜を備えた仕切板を有効活用する。【解決手段】全熱交換素子（30）は、第１主面（32a）および第２主面（32b）を有する基材（32）と、基材（32）における第１主面（32a）側に設けられた透湿膜（33）とをそれぞれ有し、互いに間隔をおいて並んだ複数の仕切板（31）を備える。複数の仕切板（31）の間に、空気が流れる第１流路（36）と、第１流路（36）に比べて水蒸気圧が高い空気が流れる第２流路（37）とが交互に形成される。複数の仕切板（31）は、基材（32）の第１主面（32a）が第１流路（36）を向き、かつ基材（32）の第２主面（32b）が第２流路（37）を向いている。【選択図】図３
